Crown Automotive CJ OEM Tach Replacement
I just got a Crown Automotive CJ OEM Tach Replacement part #5459418 off E-bay. My 85 CJ did not come with one, so in keeping with OEM style I went with this one. Hook up instructions appear pretty straight forward. However, I need to cut a hole in my dash to install. (1) Does anybody know if drilling a 2.75" hole is the correct size for mounting this tach? (2) I have a 94 YJ 4.0L in my CJ, I am assuming I put the cylinder selecter switch to 6 cylinder or am I missing something? (3) I have a white wire coming out of the tach that connects to the CJ dash illumination wiring. What/which wire in the CJ dash do I connect this wire to for tach illumination? Thanks Guys for your help.
